Effective Defect Prevention Approach in Software Process for Achieving Better Quality Levels

TL;DR

This paper emphasizes the importance of defect prevention in software development, demonstrating that effective inspection and testing can eliminate up to 99.75% of defects, thereby improving software quality and reducing post-deployment issues.

Contribution

It provides an analysis of defect prevention methods across five projects, highlighting inspection and testing practices that significantly reduce defects and improve software quality.

Findings

Inspection can eliminate up to 99% of defects.

Testing accounts for 25-30% of project effort to achieve high defect removal.

Different companies vary in inspection and testing ratios, affecting defect prevention effectiveness.

Abstract

Defect prevention is the most vital but habitually neglected facet of software quality assurance in any project. If functional at all stages of software development, it can condense the time, overheads and wherewithal entailed to engineer a high quality product. The key challenge of an IT industry is to engineer a software product with minimum post deployment defects. This effort is an analysis based on data obtained for five selected projects from leading software companies of varying software production competence. The main aim of this paper is to provide information on various methods and practices supporting defect detection and prevention leading to thriving software generation. The defect prevention technique unearths 99% of defects. Inspection is found to be an essential technique in generating ideal software generation in factories through enhanced methodologies of abetted and unaided inspection schedules. On an average 13 % to 15% of inspection and 25% - 30% of testing out of whole project effort time is required for 99% - 99.75% of defect elimination. A comparison of the end results for the five selected projects between the companies is also brought about throwing light on the possibility of a particular company to position itself with an appropriate complementary ratio of inspection testing.
